To all whom) it may concern Be it known that I, JOHN A. PINDELL, ofCockeysville, in the county of Baltimore and State of Maryland, haveinvented certain Improvements in Bottles, of which the following is aspecification.

This invention relates to certain improve ments in bott-les which in theopening or unsealing of the same, Vare partially destroyed and therebyrendered unfit for subsequent use as sealed containers of liquids, aswill hereinafter fully appear.

In the further description of the said invention which follows,reference is made to the accompanying drawing forming a part hereof, andin which Figure 1 is a vertical central section of the improved bottle;and Fig. 2 a section of Fi 1 taken on the broken line :1c-m.

Retgerring now to the drawing, 1 is the body of the bottle shown as ofcylindrical form; and 2 and 3 are respectively, the neck and the bottomof the bottle. The interior of the neck 2 is rovided withcircumferential grooves a wiiich in a sectional view of the bottle, asin Fig. lines b.

A. portion of the bottom of the bottle is inturned, and the inturnedportion 4 is practically of frusto conical shape terminating in acentral depression c the bottom of which is much thinner than thematerial around it and being frangible can therefore be easily brokenwithout injuring the annular edge d.

5 is a spring wire or rod having its upper end bent so that when it isplaced diametrically within the neck, it will conform toV and presstightly against the grooved or 1, exhibit waved waved surface of theneck as shown inv Fig. 1.

The portion of the wire 5 which is below the grooves a, is central ofthe bottle and extends downward to within the depression c but normallyclear of its bottom, as shown.

is disk on the wire 5 to which it is preferably soldered, and 9 a rubbergasket cemented or otherwise Jfastened to the underside of the disk 7.The distance of the gasket 9 from the annular edge d on the bot-tom 3,is slightly less than the vertical distance between the annular groovesa, in order that should the wire be pushed down that distance, and theupper bend of the wire broughtfromthe upper to the lower groove a. inthe neck 2, the gasket 9, after i slightly less than the :in the neck otone of two vertical positions,

the end of the wire has perforated the bottom ot' the depression c, willbear with pressure on the annular edge d and thereby orm a tight ointfor the time being.

12 is a second disk fastened like the one 7 to the wire 5; and 13 is agasket Secured to the upper side of the second disk 12.

rIhe vdiameeter of the second diskv 12 is smallest inner diameter of theneck 2, and the diameter of the gasket 13 is greater, so that when thewire 5 is in the position shown in Fig. 1 the gasket 13 will be heldtightly against the lower edge of the neck 2'and thereby seal the bottlewith a tight joint.

'It 'will be understood that owing to the end of the spring rod 5 whichis withthe bottle, extending diametrically of the same, the ortion ofthe saidv rod whichiis in the bo y 'of the bottle is held' centrallythereof; and that in view of the annular grooves a which are at diderentheights, being alike in shape, the rod can be sprung into and rmly heldin either one position serving to tightly close the neck by means of thegasket 13, and the other to prevent, through the medium of the gasket=9,the discharge of the contents of the bottle alter the bottom of the andin consequence of this constructionv and arrangement the bottle afterbeing opened is a practical and effective container for liquids untilemptied of its contentswhen it becomes worthless for further use. as aclosed receptacle.

After the bott-le is filled, the rod 5 with its attachments, is insertedthrough the neck 2 in which operation the gasket 13 is inverted at itscircumference and maintains this form until the gasket has passed tobelow the neck, after which it is drawn up to the position in which itis shown in the drawing and the bottle thereby sealed.

To open the bottle, Vthe head of the wire 5 is struck a sharp assume thecondary its end to perforate the bottom of the depression c. At the sametime, the gasket 9 is seated tightly upon and leakage of the contents ofthe bottle thereby prevented.

After the bottle has been emptied o its contents, it can be againfilled, but not again made a sealed container for the reason that in aneffort to that end, the opening made upper depression c is fractured, v

blow which causes it to position described, and

the annular edge 63 a frangible area, and. a neck with projectionstherein at 'different heights, combined withy a rod having its upper endbent. to-

extend diametrically across the interior of the neck and engage the saidprojections, whereby it may be held in either one of two verticalpositions, and its lower end situated over the frangible, area, the saidrod carrying two gaskets one to close the neck, and

the otherl to cover the frangible area when the rod is forced downand'its end through the same, substantially as specified.
